MAGNETIC VENTILATOR SYSTEM.

Original application trol the ventilator openings, 'moreparticularly for Water-tight bodies described in my pending application, Serial No. 159,184

this application being a division of said apQ plication.

- One object of the present invention is to provide a positive closing mechanism that will close the ventilator when the body tilts a predetermined distance.

Other objects and advantages will appear.

Figure 2'is a view taken substantially along line 2-2 of Figure 1. I A A water-tight body 60, with" double wall and insulation-in centre, preferably of cork,

of any suitable configuration, is securely mounted on the frame 10, it having a windshield 61 secured inthe front end'thereof. An opening 64: is provided, in this, instance,

inthe top of 'the body for ventilation purposes; A closure 65 is hingedly mounted as at- 66 to -close the opening 64 whenever desirablesuc'h as when the vehicle passesfrom land to water, it being desirable to exclude all waterfrom within the body As shown,

I the closure 65, is automatically operable responsive to'tho tilting ofthe body occuring when the-vehicle passes. from land to water so that'there will be no possible chance i of the interior of the body becoming flooded.

vMeans for automatically closing the' closure 65, in the present embod ment consists of electrical magnetic means including an elec- 'tro-magnet 67 having an iron core 68in, the
